Methodology

Our estimates are based on total earnings from May 2011 to May 2012—the amount of money an act makes from record sales, touring, endorsements, merchandise sales and other ventures before subtracting management fees, legal costs and taxes (which can gobble up the bulk of a big payday). The totals were compiled with the help of data from Pollstar, RIAA and others, as well as interviews with industry insiders including concert promoters, lawyers, managers, agents and, in some cases, the musicians themselves.
